Here, the connecting pipe 261, the fixing pipe 262 and the intubation tubes 263 play a role in guiding the flow.
[0029] Specifically, the working principle of the multi-functional nasal drug delivery device for mice is as follows: during use, by rotating the first threaded rod 231, the lifting plate 232 moves upward under the action of the first limiting rod 234 to open the clamping plate 233, and then the mouse is placed in the placement groove 221. At this time, rotate the first threaded rod 231 in the reverse direction to make the lifting plate 232 move downward and clamp the mouse through the clamping plate 233. At the same time, the limiting plate 243 is stuck on both sides of the mouse's neck, and the trapezoidal sleeve 241 is stuck on the mouse's mouth for positioning and exposing the nostrils. At this time, the connecting pipe 261 is connected to the output end of the micro drug reservoir 120, and the connecting pipe 261 is placed in the arc-shaped groove 133 and heated by the heating element 130. At this time, rotate the second threaded rod 251 to make the movable plate 252 move downward. During the downward movement, manually rotate the fixed pipe 262 to adjust the insertion angle of the intubation tube 263 so that the intubation tube 263 is inserted into the nasal cavity of the mouse. Then, the micro pump 110 works to push the micro drug reservoir 120, so that the liquid medicine in the micro drug reservoir 120 enters the nasal cavity of the mouse through the connecting pipe 261, the fixed pipe 262, and the intubation tube 263. In this way, the liquid medicine can be conveniently heated during the drug delivery process, and at the same time, the mouse can be positioned and fixed, improving the stability of drug delivery and making it more convenient to use with more diverse functions.
